Investors in POET Technologies are navigating a stark divide, with a freshly filled $400 million capital cushion on one side and a federal class-action lawsuit on the other. The stock ended Monday at $9.85, up 4.34% on the session, but the intraday range of $8.68 to $10.06 and trading volume of over 24 million shares underscore just how jittery sentiment remains around the photonic chipmaker.
The equity has been on a rollercoaster. Over the trailing twelve months it has rallied roughly 97%, yet it has tumbled more than 27% in the past 30 days alone. At €8.70, the stock trades about 54% below its 52-week peak of €18.84 touched in May, and below its 50-day moving average of €10.48. The 200-day average of €6.72 still offers technical support, but the annualised 30-day volatility of 122% tells the real story: every fresh headline moves the needle hard.
Legal headache from two directions
The most immediate overhang is the class action filed by Faruqi & Faruqi. Investors who bought shares between 1 April and 27 April 2026 had until 29 June to register as lead plaintiff — a deadline that has now passed, though the litigation itself continues. The complaint centres on allegations that POET and its managers made false or misleading statements about two things: the company’s potential PFIC tax classification and its business agreements with customers.
The trigger came on 27 April, when POET disclosed that Celestial AI had cancelled all orders, including the initial production units announced back in 2023. Marvell Semiconductor, which had acquired Celestial AI, delivered the cancellation notice in writing on 23 April and also accused POET of publicly releasing confidential order and delivery details. The disclosure sent the stock into a tailspin and provided the factual basis for the lawsuit.
Separately, the PFIC question had already surfaced on 14 April. POET said it expected to be classified as a Passive Foreign Investment Company for fiscal 2025 — a designation that can trigger punitive US tax treatment for American holders unless they make a QEF election. Management added that it does not expect PFIC status for 2026 and reiterated plans to relocate its headquarters to the US, subject to approvals. The company insists its broader business is intact, pointing to a separate $5 million order with another technology firm that remains in execution.
Should investors sell immediately? Or is it worth buying POET Technologies?
The $400 million counterweight
While the legal drama unfolds, POET has significantly strengthened its balance sheet. On 18 May, the company closed a capital raise that saw one institutional investor subscribe for roughly 19 million new shares and an equal number of warrants at $21.00 per security — slightly above the prior day’s close. The total proceeds: $400 million. Management plans to deploy the cash into manufacturing infrastructure, acquisitions, research, and the company’s light-source business.
Since that financing, the official news feed has gone quiet. The annual shareholder meeting on 26 June offered no new commercial announcements; CEO and Chairman presented a strategic framework dubbed “The Three Cs of POET’s Success: Credibility, Capacity, Capability” but no fresh customer wins. Monday’s rally therefore ran on market dynamics alone, not on a new press release.
What comes next
The lawsuit is still in its early stages, and until a settlement or verdict emerges, the legal uncertainty will remain an independent drag on the share price — regardless of how the operational side progresses with AI data-centre optics and optical interconnects. The after-hours level of $9.99 suggests buyers are still willing to step in, but the 52-week range of $3.87 to $20.81 is wide enough to absorb any shift in sentiment.
For now, the next catalyst for POET is less likely to come from a lab breakthrough than from a courtroom procedural update — or, ideally, from a concrete customer win that demonstrates the Celestial AI cancellation was an isolated event rather than a symptom of a deeper marketing problem. With $400 million in fresh capital and a stock that has given back more than half of its May peak, the setup is as polarised as the asset itself.
